DIY Boost Converter How to step up DC voltage efficiently
video description
led acid battery replacement.
how:
sell 6 ultracaps instead of led acid battery and with it you get a 9v battery boost converter to 14volts gizmo that you use in case of not using your car for more than a few days so you can charge your caps so the car starts and than you got the alternator doing less work, you got a lighter car. Or. instead of 9v battery a small sollar pannel so you have your starting current always ready.

iam making this right now but i got problem uploading the code. TCCR1 is not declared is scope. Im using arduino uno by the way. any fix for this?
Update: I rename TCCR1 to TCCR1A but got next error PWM1A is not declared in scope. I guess this code are only for ATTiny as their header file includes it? can anybody help me fix the code so I can upload it to uno? Thanks

I tried it using an Arduino to PWM the MOSFET gate from 100 to 1000 Hz, duty cycle roughly 50%. I ran a small DC motor with it with the inductor, diode and capacitor in place, but no voltage gain. I used a small 9V battery as the power supply. Could this be due to the power-hungry nature of the motor?

Your videos are great, you explain in great detail so that anyone can follow along. However I have a question, How did you get the mosfet frequency all the way up to 32. 5 kHz? Even if i copy the same code, I can only reach about 32 Hz. Anything higher requires a pwm library, but I didn't see you using one?

Is it possible to make a boost converter with the astable multivibrator and use the feedback without any op-amps or micros, because my input voltage is too low from 0. 7 to 1. 6 volt? I know that joule thief circuit work at this voltage, but unfortunately, it does not efficient like boost converter.

So any contraption on the internet without the 555 timer or AT microcontroller doesn't provide constant voltage in case of changing load? Do I even need such a feature for powering a regular 12V 140 mm CPU fan from USB?

You're pro in electronics. Sad that u just make codes for electronics not for something else. I wish if u would try going in AI programming cuz u will be the perfect person having experience and knowledge of all fields

Man, I think you need to slow down - boost converters are not this complex. So when you make yours in this way It's not that complicated is the exact opposite of what you mean. Great that you handled it's oddities though.

love how the video ends with the thing going up in smoke.
How did you determine the 100 mH inductor? was that random? I assume a larger value would get you higher current but lower max voltage?

What exactly is the purpose of R1 & R2? I meat the Pulldownresistor on the MOSFET-Gate and the Resistor between the uC-Output and the MOSTET-Gate. Are they important?
